Sažetak:
Network providers need very effective optimization tool for good utilization of scarce link capacities during finite exploitation period. In the case of multiple link capacities with mutual traffic correlation such problem could be more demanding. The problem is explained for satellite link, but it could be applicable for other transmission resources. Mathematical model for optimal capacity sizing of N different link elements (capacity types) is explained, minimizing the total expansion cost on getaway link (G-link) by new constructions on the Earth. Instead of nonlinear convex optimization technique, that could be very exhausted, the network optimization method is applied. With such approach an efficient heuristic algorithm for three different capacity types is being developed. Through numerical test- examples it shows high efficiency and significant complexity savings, giving us close to optimal result. However, in real circumstances some adding limitations on capacity state values can be introduced. From testing is obvious that heuristic option M_H (with only one negative value per capacity state) shows the best ratio between complexity and result deterioration.
